PROCESS OF PRODUCING PATTERNS ON METAL FABRICS.

Specification of Letters Patent.

Patented Jan. 1'7, 1911.

Application filed June 23, 1910. Serial No. 568,509.

To all whom it may concern:

Be it known that I, RICHARD DOLLINGER, a subject of the German Emperor, and residing at Pforzheim, Baden, German Empire, have invented certain new and useful Improvements in Process of Producing Patterns on Metal Fabrics, of which the following is a specification.

My invention relates to a process of producing so-called through and through patterns on wire-ring and other metallic fabrics. According to prior methods fabrics with pattern of this kind have been composed of separate fragments of difierent colors, or of variously colored rings, whereas I produce the pattern by chemical or electrochemical means.

The invention is illustrated in the accompanying drawing, which shows the application of the process to the pocket of a metal ring-fabric hand-bag, or reticule.

Figure l is an elevation of a plate used to support the fabric pocket or the like, and Fig. 1 is a plan thereof. Fig. 2 is an elevation of this plate with the pocket slipped over it, and Fig. 2 is a plan thereof. Fig. 3 is an elevation of the plate with pocket placed between two soft stencils, and Fig. 3 is a plan thereof. Fig. A is an elevation of the assembled parts located between two hard stencils, and Fig. P is a plan thereof. Fig. 5 is an elevation of the entire assem blage locked in an openwork frame, and Fig. 5 is a plan thereof. Fig. 6 is an elevation of the pocket, the left-hand half of the figure. showing the pocket after metal has.

been deposited to form a part pattern, while the right-hand half shows the same after this part pattern has been completed by a second similar operation.

Hitherto through and through patterns have been produced on metal fabrics by connecting together differently colored, regularly confined, pieces of fabric, or by looping together little rings or the like of divers colors. Such purely mechanical method of procedure, however, is obviously extremely tedious and troublesome.

According to my invention I produce the through and through pattern more simply, rapidly and cheaply by a chemical or electrochemical method. For this purpose the piece of fabric a which is to receive the pattern, and which by way of example is here shown as being the complete pocket of a metal ring-fabric hand-bag, is laid or slipped over a plate I) (Fig. 1) of insulating material, in the manner shown'in Figs. 2 and 2. Hereupon sheets (Z of wax, guttapercha or the like substance, provided with slots c'corresponding with the pattern desired, are applied at each side of the fabric, as shown in Figs. 3 and 3 Slotted pattern-plates f of vulcanite or other suitable material are next laid against the soft stencils d, the openings 6 in the former registering with the apertures c in the latter, (Figs. 4 and 4 The hard stencils or plates 7 are for the purpose of exerting a uniform pressure on the soft stencils cl on the subsequent pressing operation. The whole assemblage of parts is now brought between two gratings, grids, or other openwork frames g and pressed together, the screw-bolts h, which pass through the frames 9 and the pattern plates f, serving to prevent possible shifting of the assembled members (Figs. 5 and 5*). By means of this pressing it is manifest that the soft sheets 0? will be forced through the ringfabric a, so that the two halves of the latter will be completely embedded in the soft mass of wax, with the exception of the parts which lie opposite the holes 0. The entire assemblage is finally introduced into a metal bath suited to produce the desired pattern, and, either with or without the application of the electric current, a colored deposit or coating produced, depending upon the na ture of the bath, at the exposed parts of the metal fabric a. The pressing device and auxiliary members are hereupon taken apart and the surplus wax cl removed, the fabric a now presenting a pattern as depicted in the lefthand half of Fig. 6.

By repetition of the steps above described, 95 i and by the employment of soft stencils having different apertures, a fabric can be obtained presenting a through and through pattern as shown in the right-hand half of Fig. 6. After the fabric has been thoroughly cleaned, etc., it can be further worked up as required. By changing the stencils, the most various plain or variegated through and through patterns can be produced on metal fabrics of rings and the like, whether on finished pieces or on lengths of fabric.

The employment of stencils in the produc tion of patterns on metal surfaces by metallic deposits in itself forms no part of the present invention. L

Having thus described my invention, I declare that what I claim as new and desire to secure by Letters Patent is- 1. The process of producing patterns on metal fabrics, consisting in embedding the fabric in a perforated plastic mass, and'in causing a metallic deposit at the exposed parts, substantially as described.

2. The process of producing patterns on metallic fabrics, consisting in first placing the fabric over insulating material, second in placing sheets of wax provided with a pattern ofthe same configuration as that of the fabric on opposite sides of the latter, the pattern of the sheets of wax registering With the pattern of the fabric, third in placing pattern plates in contact with the sheets of 1', wax, then in subjecting the whole to pressure, and finally in causing a metallic deposit at the exposed parts.

3. The process of producing patterns on metallic fabrics, consisting in embedding the topressure, and in causing a metallic deposit at the exposed parts.

In testimony whereof I affix my signature in presence of two witnesses.

RICHARD DOLLINGER.
